One of the best-known single-phase multiferroics is BiFeO3(ref.4), which possesses large spontaneous polarization (~100 μC/cm2) driven by the stereochemical activity of lone-pair electrons of A-site Bi3+ions and weak magnetization, due to the canted antiferromagnetic ordering of B-site Fe...
Therefore, the high volatility lead-based ferroelectrics pose an environmental concern and are also detrimental to human health4–6. To create awareness of environmental safety, restrictions were imposed by Waste 1Department of Physics and Astronomy, National Institute of Technology Rourkela, Rourkela...
Our results demonstrate the engineering of asymmetric layered structures with emergent ferroelectric and magnetic field tunable functions distinct from that of normal devices, for which the components are typically ferroelectrics. 1 Electron Complexity Laboratory, Institute of Electronic Structure and Laser, ...

However, to facilitate the search in the multi-parameter space and open the way for further FEM, here we elaborate the analytical theory. Analytical solution in harmonic approximation To explore the phase evolution in the system described by the free energy, Eq. (1), we consider the ...
One possible route for designing single-phase multiferroic materials is to start from a series of well-established ferroelectrics and create additional functionality by incorporating magnetic ions into these systems1,8,9. A promising class of materials for this purpose is the so-called Aurivillius ...
